Well I haven't tried this before but you could put some rescue remedy in their water. Here's a link about it:http://www.drsfostersmith.com/produc...fm?pcatid=3550. I don't know if you can buy this at a pet store or not. Good luck.

By the way, how old is Mr. Spunky? My Blaze has no fear of my other cats and he also likes to bug them a lot. He acts like he doesn't understand what hissing and growling mean. Alani is a bit better about this but he still has his buggy moments too. They're both only a year old so they still have a lot of kitten energy in them.
